Old City's most photogenic ice cream parlor feels like it was lifted straight from 1910 and dropped onto Market Street. The Berley brothers run it with a commitment to the bit: costumed soda jerks work the counter, antique fixtures line the walls, and the ice cream itself is serious enough to justify the aesthetic. Order the Mt. Vesuvius if you want the full show, or grab a scoop in a takeout container and eat it while you walk the neighborhood.
